EFFIE I. JOHNSON, OF KANKAKEE, ILLINOIS.

GAS BURNER.

Application filed April 3, 1924.

To all whom it may concern:

Be it known that I, Errm J. JOHNSON, a citizen of the United States, residing at Kankakee, in the countyof Kankakee and State of Illinois, have invented certain new and useful Improvements in Gas Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention provides a burner adapted to use gas as fuel and which is designed particularly for cooking purposes, said burner being preferably of cast metal and comprising concentric passages cored therein and provided with gas outlets.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention.

Referring to the accompanying drawings forming a part of the application:

a Figure 1 is a top plan view of a burner embodying the invention,

Figure 2 is a longitudinal section thereof on the line 2-2 of Figure 1,

Figure 3 is a transverse sectional view on the line 33of Figure 1,

Figure 4c is a sectional View on the line 4:74 of Figure 1,

Figure 5 is a front View of the gas inlet,

Figure 6 is a front view of the damper, and

Figure 7 is a side view of a modified form of gas intake.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The burner is preferably of cast metal and is cored to provide a plurality of concentric chambers or passages, the center chamber 10 being broad and the outer chamber 11 being narrow and of annular formation. The several chambers have flat bot- Serial No. 704,024.

toms, whereas their sides slope upwardly and are provided at the top with outlets 12 from which the gas issues in jets; A radial passage 13 is in communication with the several chambers and increases in depth from the center of the burner outwardly towards the edge thereof, whereby to equalize the supply of gas to the several chambers. The gas intake is fitted to the outer end of the radial passage 13 and comprises a nipple 14 and a flared portion 15, the outer face of which is flat and provided with a central opening 16 and outer openings 17. A bushing 18 is fitted to the opening 16 and is adapted to receive the fuel pipe, not shown. A damper 19 is mounted upon the bushing 18 and held in place thereby and is provided with a central and outer openings to register with the respective openings 16 and 17 of the intake. The nipple 1 1 is straight, as shown most clearly in Figure 2, or deflected as indicated at 14? in Figure 7.

The numeral 20 designates a rod which forms a support for a rest 21 upon which the burner is mounted, said rest consisting of a strip of sheet metal crimped or bent into approximately theoutline of the letter so as to straddle the rod 20 and support the burner.

This gas burner will give equal heat over the entire area of the burner and because of the fact that the time requi ed for cooking .a given amount of food is shortened by the distribution of the heat over a larger area of the cooking utensil the gas consumption is not increased over that of the burners now in use.

What is claimed is A cast metal gas burner provided with a plurality of concentric chambers, the sides of which slope upwardly and have outlets in the top, and a radial fuel-supply passage in communication with the several chambers and gradually increasing in depth from the center outwardly, said passages being the sole means of communication between the chambers.

In testimony whereof I afiix my signature in presence of two witnesses.
